ALL ABOUT PORTOCORK–THE WORLD'S FINEST CORKPortocork America is the premier supplier of natural cork closures to the North American wine industry. For nearly a quarter-of-a-century, our company has produced a wide range of natural cork closures, ranging from high-end still and sparkling wine cork to Twin Top® and Neutrocork® products designed for value wines.
As a wholly-owned subsidiary of the Amorim Group, the world's largest and most recognized name in cork production, Portocork is proud to be the first in our industry to screen every single United States-bound cork bale for 2,4,6-trichloroanisole (TCA) using gas chromatography mass spectrometry (GC/MS). Since 2001, we have experienced an 80% reduction in TCA scores through the use of this technology.
Portocork America was established in 1983 through a partnership between Portocork International and Fleming Packaging Group of Napa. The partnership continued until 1996 when Portocork International acquired 100% of Portocork America.
Portocork was a founding member of the Cork Quality Council (CQC) which was established in 1993 with the goal of continuing to increase quality standards and awareness of the benefits of natural cork. Portocork co-sponsored TCA research that was conducted jointly by the CQC and ETS Laboratories to establish a non-subjective cork testing methodology using GC/MS. Portocork continues as an active CQC member today.
Portocork International, located in Santa Maria de lamas, Portugal, is the world's most technologically-advanced producer of cork. Portocork has developed ultra-modern production facilities to process natural cork which is sourced only from company owned and leased natural forests that have existed in Portugal for decades. We control the cork from the time it is harvested until it arrives at your winery. This complementary combination of centuries-old natural practices and state-of-the-art production facilities, along with rigorous testing both in our ISO-9002 certified Portuguese facilities (with in-house GC/MS) and our California facility located in the Napa Valley, assures that our cork is the highest quality and most consistent cork year after year. Portocork America provides the world's finest cork.
